SPRAY-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 730,927, dated June 16,1903. Application filed November 13, 1902. Serial No. 131,125. (Nomodel.) I

- T0 at whom it may concern:

Be it known that 1, AUGUST J KOEGLER, a citizen of the United States,residing at Milwaukee, county of Milwaukee, and State of IVisconsin,have invented new and useful Im- Figure 1 is an exterior view of thenozzle and a portion of a hose connected therewith.

Fig. 2 is a central longitudinal sectional view of the same. Fig. 3 isa-plan view of the rotary fluid-distributing cone which produces thespray. Figs. 4, 5, and G are views of a modified form of constructioncorresponding, respectively, with the views given in Figs. 1, 2, and 3.

Like parts are identified by the same reference characters throughoutthe several views.

1 is a cylindrical coupling-head, reduced at 2 and provided with anozzle-tip 3, having an aperture 4, through which the fluid escapes. Thecoupling head is interiorly screwthreaded. 5 is a ring screwed into thecoupling-head, and 6 is an annular packing-collar, against which the endof the hose-coupling '7 abuts when screwed into the coupling-head 1. Arotary water-distributing cone 8 is located between the ring 5 and thetip 3. This cone is preferably formed by pressing a circular sheet-metaldisk into conical shape, corre sponding substantially with the taperedportion 2 of the nozzle. The cone 8 is provided with slits 10, and theedges of the plate composing the cone are offset along the slits to formapertures through which the water passes, the material between any twoof theislits taking the form of a segmental blade with a spiral pitch.

When water or other fluid is discharged through the nozzle, the pressureupon the spirally-inclined surfaces of the cone 8 causes the latter torevolve,-while-the water passing through the slits in the cone holdsthe.cone by back pressure away from the tapered portion 2 of the nozzle,the cone thus being caused to revolve freely in the water withoutfriction on the inclosing walls of the nozzle.

The end or tip of the nozzle is preferably provided with a countersunkbore forminga comparatively sharp edge 11 around the aperture l; Thewater in passing the cone 8 receives a whirling motion and on strikingthe edge is subdivided into a fine spray. It will be observed that theaperture 4 is of less diameter than the interior of the nozzle-tip 8.This also facilitates splitting up the stream into a spray.

Referring to Figs. 4, 5, and 6, it will be observed that theconstruction is the same as that of Figs. 1', 2, and 3, with theexception that the distributing-cone is provided with spirally-extendingchannels 12 on its outer face. The cone is also provided with aforwardly-projecting stem 14, which extends through the tip of thenozzle and projects centrally through the aperture 4 therein. Vhere thestem 14 is used, a finer spray-is produced with a given volume andpressure of Water. The spiral channels 12 in the cone shown in Figs. 5and 6 do not extend through the cone, except at the outer edges. In thisconstruction the water escapes past the base of the cone through thenotches formed by the spiral channels 12 and is directed by the channelstoward the apex of the cone. In practice sufficient water passes intothese channels to press the cone backwardly away from the taperedportion 2 of the nozzle in the same manner as above described withreference to the cone shown in Figs. 2 and In the constructions shown inFigs. 4, 5, and (3 the cones are preferably formed of cast metal, whilein the construction shown in Figs. 1, 2, and 3 they are preferablystamped from sheet metal. In either case passages are formed on theouter surface of the cone at an angle to the radii thereof, whereby thestream of water is given a whirling motion, and it is not materialwhether such passages consist of the broad shallow depressions formed byoffsetting the metal of the cone between the slits 10, as shown in Fig.3, or of the channels 12. (Shown in Fig. 6.)

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a device of the described class, the combination with anozzle-casing, of a water-' distributing device loose in the casing, andprovided witha spirally-formed outer sur-- face, said nozzle beingcontracted in advance of said device, and provided with -an-aper turedtip.

2. In a device of the described class, the

combination with a nozzle-casing, of a-waterr; distributingdevice loosein the casing, and provided with a spirally-formed outer sur-& face,said nozzle being contracted in advance of said device, and providedwith an-aper-Q' tured tip formed with an inWardly projecti-ng edgearound the aperture.

3. In a device of the described class, the combination with anozzle-casing,-provide-d5 with atapering portion, and an apertured tip;

and a water-distributing device tapered in";

correspondence with the casin g, and provided,- on its tapered surfacewith depressions-'eX-l tending at an angle to the radii of the device.

4. In a device of the described class, the; combination with anozzle-casing, provided} with a tapering portion, and an apertured tip.and a waterdistributing device tapered in correspondence with thecasing, and provided on its tapered surface with depressions eX-;tending at an angle to the radii of the device, said device being alsoprovided withaper tures for the passage of fluid to the tip.

5. In a device of the described class, the

combination with a nozzle-casing, provided with a tapering portion, andan apertured tip and a Water distributing device tapered incorrespondence with the casing, and provided on its tapered surface withdepressions extending at an angle to the radii of the device; togetherwith means for permitting fluid to pass through the casing in thedirection of the tip, and directing the same along said proj ections.

ture; and a water-distributin g device located in the casing, saiddevice comprising a conical plate having-slits, and having-its outersurface 1 formed to "receive pressure of fluid passing through the'slitsat an angle to the axis-of the cone,-whereby the latter is rotated.

8. In a device of the described class,= the combination with anozzle-casing, provided witha tapering portion,-and an-apertured tip;and a water distributing device tapered in correspondence with thecasing,'and provided on its-tapered surface with depressionsextendingat'an angle to the'rad-ii of the device;

together-with a stem extending from said device through the aperture inthe tip.

9.-In"a device of the described class, the combination with anozzle-casing} provided with a tapering portion; and-anapertured tip;and a water distributing device tapered in correspondencewith thecasing,-an'd provided on its'tapered surface with depressions extendingat an angle to the radii of the=deviceg together with a forwardlyprojecting stem connected with said device.

In testimony whereof I affix mysig-nature in the presence oftwowitnesses.
